"The final product is good and the price was good. The structure all seems to be high quality and with double pane windows it can hold the climate or out well as needed. With screens all around we can let the air move through when we want. The design process was a good experience, but we were not warned that our decisions in dimensions would result in difficulties with regulations and the electrical work. The lack of communication between sub-contractors during the process resulted in several delays. There were times when we were told there would be hand-off and it didn't happen until we prodded them. We kicked it off in the early spring and it didn't complete until August. Early on, the delays were unavoidable due to weather and ground conditions but after the foundation was in it took to long to complete the structure. The problem is not specifically the total time to complete but being left with very little time to replace the yard and driveway before winter."

I've been in the trades since I was 15, looking for opportunities to grow my buisness after moving to a new area recently. We generally are a group of full time contractors, engineers and project managers that like to get our hands dirty. We work fast, do everything in house, work flexible hours and pride ourselves on affordable pricing.

"I recently had the pleasure of working with Emerald Bay Design and Construction for a major renovation project, and I couldn't be more impressed with the craftsmanship. From start to finish, they demonstrated a deep understanding of design and construction techniques, delivering outstanding results that exceeded my expectations. Richard took the time to understand my vision and translated it into a beautifully crafted reality. Communication was clear and timely throughout the process and I received my bid back quickly and accurately. Overall, I would highly recommend Emerald Bay Design and Construction to anyone looking for a design and construction company. I am thrilled with the results of my project and look forward to working with them again in the future."

"My interaction with this company, represented by Gordon Rudd, was limited to a site visit only. Work that I thought might be needed turned out to be unnecessary. When I called the company, I reached Gordon directly, and he was able to stop by the next morning, right at the time we scheduled. He was very helpful in explaining what I was seeing. He didn't charge me anything for the very helpful visit."

FAQs for shelter or outbuilding building service projects in Lake Geneva, WI

A bomb shelter is an abode built to withstand disaster. Bomb shelters may refer to a space or bunker that can protect inhabitants through a hypothetical nuclear attack, apocalypse, or any other massive crisis. People usually build bomb shelters underground and stock them to live there a few days to a month at a time. Doomsday bunkers accommodate long-term living rather than just through a short crisis.

Builders construct bomb shelters with reinforced steel, box culvert, concrete, or other durable materials (but many professionals do not recommend shipping containers, as they’re not designed to live underground. If building underground, you’ll first have to excavate land before building the actual structure. You’ll have to implement air and water filtration systems, septic systems, and power supply.

It takes a lot of experience to safely and legally construct a bomb shelter, not to mention make sure it’s fit to live in for extended periods of time. It’s best to talk to a residential structural engineer near you for proper guidance.

The current standard filtration systems require filtering both air and water. For air, you’ll want an NBC filter system, which both domestic and international producers make. NBC stands for Nuclear, Biological, and Chemical, which filters out all three. If you’re only building your shelter for natural disasters, chemical attacks, and biological attacks, you may opt for the less expensive HEPA filter system. 

Water filtration requires the same level of care. You’ll likely want to have a large water storage capacity to survive short-term disasters. For long-term living, you’ll want to have a water filtration system.

Rising S bunker prices depend on the size, ranging anywhere from $20,000 to $9 million. Their least expensive model is 96 square feet while their most expensive model has a gym, swimming pool, hot tub, and bowling alley.

  • Mini: $45,500

  • Standard Bomb Shelter: $67,500–$109,500

  • Silver Leaf: $140,000–$182,500

  • Admiral: $180,000–$500,000

  • Xtreme: $450,000–$780,000

  • Xtreme Bunker Complex: $840,000–$1,830,000

  • Luxury Series: $3,800,000–$9,600,000

You almost always need a permit to build a bunker on land with any type of public utilities running through it. You’ll want to check with your local building code enforcement agency to see if this is the case for your area. 

Because you’re building a structural component that often requires electricity, water, and sewage services, you’ll need to apply for permits to attach these utilities to your new property. However, off-grid-only units in rural areas may not need all or any of the permitting you’d normally find in more urban settings.

To survive a nuclear blast, you’ll need to have your bunker at least three feet underground. However, it’s usually advisable to put it further underground. To survive a close strike, you’ll want to have the bunker at least 10 feet down and with five-foot thick reinforced concrete. However, knowing exactly how deep to build depends on the size of the blast you’re trying to avoid. Most bunkers don’t need to be more than 5 feet below the ground.
